A sealing apparatus is disclosed. In some implementations, the sealing apparatus includes a process chamber having an internal space, a cell loading portion configured to load a plurality of battery cells and enter the internal space of the process chamber, a plurality of sealing units disposed in the internal space of the process chamber, the plurality of sealing units configured to partially seal the battery cells, respectively, and a driving portion configured to move the plurality of sealing units such that the plurality of sealing units come into contact with the plurality of battery cells, respectively.

Sealing apparatus for battery cell

A secondary battery and a battery pack including the secondary battery are disclosed. According to one aspect of the present invention, the secondary battery includes: a waterproof part configured to surround at least a portion of a circumference of the electrode assembly so that a gas within the exterior passes through the waterproof part, but a liquid within the exterior does not pass through the waterproof part; and a vent part provided in an inner surface of the exterior to provide a path through which the gas within the exterior is discharged to the outside when an internal pressure of the exterior exceeds a certain value.

Secondary battery and battery pack including the same

In order to more accurately measure internal pressure of a secondary battery, the present disclosure provides a measurement method including (a) interposing the secondary battery between an upper plate and a lower plate, (b) increasing internal pressure of the secondary battery by injecting a gas into the inside of the secondary battery, (c) monitoring surface pressure of the secondary battery at a measuring member which is in contact with the lower plate, and (d) measuring a value of the surface pressure from the measuring member at a point in time when at least one sealing portion of the secondary battery is vented.

Secondary battery internal pressure measurement method

Provided are methods and apparatuses for improving compression efficiency in directional intra-prediction. A video encoding apparatus, which does not need to record intra mode information, includes a mode selector that selects one from among a plurality of intra modes on the basis of a directionality of at least one neighboring block that has already been reconstructed before a current block is reconstructed, an intra predictor that obtains a prediction block of the current block from the at least one neighboring block according to the directionality of the selected mode, and obtains a residual block by subtracting the prediction block from the current block, and a unit for encoding the obtained residual block.

Video encoding apparatus, video decoding apparatus, and video decoding method for performing intra-prediction based on directionality of neighboring block

A case opening apparatus is disclosed. In some implementations, the case opening apparatus may include a suction portion including a first suction portion configured to suction an upper portion of a case of a battery cell being in a folded state and a second suction portion configured to suction a lower portion of the case, and a rotation driving portion configured to open the inside of the case by rotating the first suction portion.

Case opening apparatus

A carrier includes a base assembly movably coupled to a transfer rail, a seating plate disposed above the base assembly and having a battery cell seated on an upper surface thereof, a pressurizing and fixing portion for fixing the battery cell to the seating plate by pressurizing the battery cell, and an elastic member for pressurizing the pressurizing and fixing portion toward the seating plate side, wherein the pressurizing and fixing portion is coupled to the base assembly to move in a first direction, which is a horizontal direction, and a second direction, which is a vertical direction.
